BATTERY-BOX.

Specification of Letters Patent. Patented Feb 22 1921 Application area August is, 1919. Serial No. 318,115.

To (ZZZ whom it may concern Be it known that I, Hum 13. SULLIVAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inIBattery-Boxcs, of which the following is a full, clear and exact specification.

This invention relates to improvements in battery boxes, heretofore commonly constructed of wood plates secured together by screws or nails, the metal of which is soon corrugated by the action of acids, to which they are unavoidably exposed, and which besides make'it difficult, and sometimes impossible, to secure the boards with sufficient tightness at the corners of the boxes for preventing leakage of acids, and, especially, when subject to a spill-over from, the acid receptable. 1

The prime object of this invention, broadly stated, is to secure the several sides and bottom of a wood battery box together by means of a non-corrosive metal, which may be applied in a molten state, without injury to the wood portions of the box, and

in such a manner as will with certainty insure an absolutely water-tight joint when between the meeting portions and at the corners of the sides and bottom of the box.

Another object of my invention is to provide metallic fasteners for the joints of a box, the material of which is such that the joints may be clamped with maximum tightness during the application of the fasteners thereto and insuch a manner that there can thereafter be no yielding of or separation, at any point of the joints.

Vith these ends in View, my invention finds its embodiment in certain features of novelty in the construction, combination, and arrangement of parts, by which said objects and certain other objects are attained, all as hereinafter fully described, with'reference to the accompanying drawings and particularly pointed out in the claims.

In said drawings:

Figure 1 is a perspective view of a battery boX in which my invention finds its embodiment.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1.

Similar characters of reference indicate the same parts in the several figures of the drawing. The sides et-l, ends 5 5, and bottom 6, of the box shown in the drawings are preferably, as shown, constructed from boards of wood, of any character best at their outer ends to provide countersinks for the fasteners passing therethrough, as

indicated at 8-8, which fasteners consist of bolts 9 and 10, integrally connected, as shown inFig. 2, with a triangular corner post 11 extending from the top to the bottom of the box. The bottom board 6 of the box is provided with a number of perforations 12, transversely thereto, registering with perforations 13, through sides 4 and which, like the perforations 7, preferably flare at their outer ends, as indicated at 14, to provide a countersink for and at both ends of a rod 15 passing through the per forations 12 and 13.

In every instance the posts 11 and rods .15 are preferably molded from Babbitt metal, but may be from lead or any other material or alloy capable of successfully resisting oxidation from the action of acids, which may be cast in their operative position from pouring, following melting to a. degree sufficient for that purpose, and without injury to the wood surfaces opposed thereto.

As a means for retaining the molten metal in its operative position in the corners, a suitable mold plate indicated in dotted lines at 16, is employed, and for the bolt holes, mold plates 1.7-17, shown in dotted lines, which latter fit tightly against the outer surfaces of the end and side boards of the box, as a practical means, not only for retaining the metal in the post holes, but in the countersinks for the outer ends thereof, a similar plate 18 being likewise employed for the outer end of the rod 15, the metal. in the opposite and pouring end for which may be upset, following an overflow thereof. The molten metal is poured into the chamber formed by the mold plates 16 and the adjacent surfaces for the corners of the box and thereafter flows outwardly through the perforations for simultaneously forming posts, bolts 77 and their countersunk ends.

The inner and outer mold plates may be held in their operative positions by any suitable means for removal after the metal of the fastener has cooled sufiiciently to set, and which it does very quickly.

If desirable, the angle formed by the bottom with the side end and end boards may be tilled with a noncorrosive metal or alloy, as indicated at 19, but ordinarily this will not be necessary because the molding of the rods in their operative position operates to permanently retain the initial tightness of their joint.

While I have described a new form of connection or fasteners for battery boxes made of wood, it is to be noted that my invention includes any other form of construction by which it is practical and feasible to mold fasteners in their operative position in the walls of a wood box for secur ing tight joints between the several parts thereof, or when for strengthening purposes only, and that my invention is therefore not to be limited to the form of fasteners I have shown for carrying out my invention; that my invention includes the fastening of boxes made from wood or from any non-metallic material, capable of resisting the action of acids, such, for example, as vulcanized hard rubber, and the material commonly known and distributed on the market as fiber board, for uses and purposes other than for battery boxes, the material for the fasteners for which is adapted to resist the destructive action of acids and also chemicals other than acids, and to which they may be exposed by reason of the particular use to which the box is applied.

Having described my invention, What I claim and desire to secure by Letters Patent is:

1. A wood box provided with metallic fasteners for the joints the material of which is adapted to be molded in their operative position therein.

2. A box formed of a number of pieces of wood ointed together and locked in their operative position by means of metallic fasteners molded in their operative position connecting said joints. i

3. A box composed of a number of boards the inner surfaces adjacent the joints of which are connected by a metallic post, and bolts passing transversely through the adjacent ends of said boards, saidposts and bolts being integrally connected and molded therein.

. 4. A box, the sides, ends and bottom of which are formed of as many wood boards provided at its corners with a post, and bolts connected therewith consisting of a metal adapted for casting said bolts and posts in their operative position therein and at a temperature substantially non-injurious to the wood fibers of the box next thereto.

5. A box comprising a number of pieces of wood joined together to form side, ends,

and bottom thereof, provided withfasteners at its corners, and having its bottom of a metal. or alloy non-corrosive by the action of acids and cast in their operative position for locking the corners and securing the bottom board to the side and end boards thereof.

6. A. wooden box provided with metallic connections for the sides and bottom thereof cast therein in their operative position.

In witness whereof I have hereunto set my hand and affixed my seal this 17th day of July, A. D. 1919.
